-# Test overview:
+# The tests in this file check that the following two bugs (both now fixed)
+# do not reappear.
 #
-#   jrnlmode2-1.*: Demonstrate bug #3745
-#   jrnlmode2-2.*: Demonstrate bug #3751
+# jrnlmode2-1.*: Demonstrate bug #3745:
+#
+#     In persistent journal mode, if:
+#
+#       * There is a persistent journal in the file-system, AND
+#       * there exists a connection with a shared lock on the db file, 
+#
+#     then a second connection cannot open a read-transaction on the database.
+#     The reason is because while determining that the persistent-journal is
+#     not a hot-journal, SQLite currently grabs an exclusive lock on the
+#     database file. If this fails because another connection has a shared
+#     lock, then SQLITE_BUSY is returned to the user.  
+#
+# jrnlmode2-2.*: Demonstrate bug #3751:
+#
+#     If a connection is opened in SQLITE_OPEN_READONLY mode, the underlying
+#     unix file descriptor on the database file is opened in O_RDONLY mode.
+#
+#     When SQLite queries the database file for the schema in order to compile
+#     the SELECT statement, it sees the empty journal in the file system, it
+#     attempts to obtain an exclusive lock on the database file (this is a
+#     bug). The attempt to obtain an exclusive (write) lock on a read-only file
+#     fails at the OS level. Under unix, fcntl() reports an EBADF - "Bad file
+#     descriptor" - error.
